My buddy bought yesterday for his pc win7 new moni with hdmi, dvi, vga-port. Everything like after bed.anleitung plugged. Moni only indicates: no video signal, then: sleep mode activated. Then moni black. Whether with hdmi and or vga cable. The same problem now with his old moni. PC was not shaken, did not fall on carpet floor and all cables are stuck. Via laptop already looking for solutions - but we need tip (s), which you can also run with a black screen, since you can logically in this condition read nothing! It hurries, buddy wants to see football, emails, ebay etc…

Well then the DVI connection is set as input.

You will probably be able to choose in the options.
